does anyone know this emblem?

I'm stuck. I came across a pair of vintage moon hubcaps and can't figure out the logo. The hubcaps are chrome WRAPPED, and are heavy (old). The emblem has embossed outlines of North America (top) and South America (bottom) with a horizontal line between them. The emblem has a white painted ring around it. Know the car? or truck? Many of us are stumped.
Thanks.

Can you post a picture?

... apart from the pic request (which was what I was going to say), does this look "original" or "factory" to you, or do you think it might be something "custom" or "home-made"??
